The 53 pages that link to Soil fertility, each with the reason it gives.

• Crop rotationRelated: Rotations influence nutrient supply through crop uptake, residues, and biological fixation.

• Soil erosionRelated: Losing nutrient-rich soil can reduce crop productivity.

• Soil organic matterRelated: Organic matter contributes nutrients and improves conditions that support crop growth.

• PedosphereRelated: Fertility determines how well the pedosphere supports vegetation.

• Soil formationRelated: Parent material and organic transformations help determine nutrient availability in formed soils.

• Soil conservationRelated: Conservation aims not only to retain soil, but also to preserve its productive capacity.

• Clay mineralRelated: Clay surfaces retain nutrient cations that plants can access through soil water.

• EarthwormRelated: Earthworm feeding and casting can make nutrients more available to plants.

• NitrificationRelated: Nitrification supplies nitrate that plants can absorb, while also changing nitrogen retention.

• Cation-Exchange CapacityNarrower topic: CEC helps explain how well soil retains nutrient cations for plant uptake.

• PastureRelated: Soil fertility influences how much nutritious forage pasture can produce.

• Shifting cultivationRelated: Fertility influences how long a plot can produce crops before fallowing.

• Slash-and-burn agricultureRelated: Burning briefly releases nutrients into ash, while repeated cropping can deplete the soil.

• Soil horizonRelated: Horizon differences influence nutrient availability and rooting conditions.

• Soil profileRelated: Horizon depth and properties affect where roots find nutrients and water.

• Termite moundRelated: Termite activity can concentrate nutrients and alter soil conditions around mounds.

• AgronomyRelated: Fertility management supplies nutrients while limiting losses and damage to soil.

• GuanoNarrower topic: Guano improves fertility by adding nutrients to nutrient-poor soils.

• LeachingRelated: Loss of soluble nutrients through leaching can reduce the fertility of upper soil layers.

• Soil scienceRelated: It connects soil properties with crop growth and nutrient management.

• DecomposerRelated: Decomposition replenishes nutrients that contribute to fertile soil.

• Alluvial plainRelated: Periodic sediment renewal can replenish nutrients in cultivated parts of the plain.

• HumusRelated: Humus contributes nutrient reserves and supports biological nutrient cycling.

• Soil degradationBroader topic: Fertility is one productive property that degradation can diminish without defining all soil quality.

• ChinampaRelated: Repeated additions of lake sediment and vegetation replenished chinampa soils.

• MilpaRelated: Fallow periods and crop combinations influence how milpa fields maintain or lose fertility.

• Organic matterRelated: Organic matter supports nutrient cycling and improves several soil properties related to fertility.

• SiltRelated: Silty soils can retain water and nutrients, influencing crop growth.

• Soil amendmentNarrower topic: Amendments may improve fertility, but fertility is only one part of soil quality.

• Erosion controlRelated: Erosion can remove nutrient-rich topsoil and reduce a field's productive capacity.

• FallowRelated: Leaving land uncropped can let nutrients recover, though outcomes depend on soil and management.

• PodzolRelated: Strong acidity and leaching often leave podzol surface horizons poor in available nutrients.

• Soil testingNarrower topic: Fertility is the broader property that many soil tests help evaluate.

• ChernozemNarrower topic: Chernozem is prized for fertility, although management still determines crop performance.

• Soil acidificationRelated: Low pH changes nutrient availability and can reduce crop productivity.

• Soil surveyRelated: Mapped soil properties help estimate crop potential and identify management needs.

• Volcanic soilRelated: Volcanic soils can be nutrient-rich yet restrict phosphorus or other nutrients through fixation.

• Agricultural landRelated: Fertility limits what agricultural land can produce without amendments or careful management.

• Multiple croppingRelated: Repeated harvests can draw down nutrients unless fertility is replenished.

• Soil chemistryRelated: Chemical measurements help diagnose nutrient limitations and guide amendments.

• CloverRelated: Nitrogen fixed by clover can increase fertility for subsequent crops.

• Tropical horticultureRelated: Heavy rainfall can leach nutrients, making fertility management central to tropical crop production.

• Macrotermes bellicosusRelated: Termite activity can concentrate nutrients and modify soil around mounds.

• Earth (soil and ground)Related: It determines how well soil can sustain crop growth.

• EdaphologyRelated: It translates soil properties into a central practical question: whether crops can obtain enough nutrients.

• Plant litterRelated: Litter returns nutrients and organic matter that can improve soil fertility.

• RhizobiaRelated: Rhizobial activity can improve nitrogen availability, a key component of soil fertility.

• Agricultural cycleRelated: Fertility influences crop growth and the need for amendments between seasons.

• History of organic farmingNarrower topic: Maintaining fertility became the organizing principle of many early organic methods.

• LoamRelated: Loam’s nutrient retention can support fertility, though texture alone does not guarantee it.
